A uniform rope of length L and mass m1 hangs vertically from a rigid support.A block of mass m2 is attached to the free end of the ropes. A transverse pulseof wavelength λ1, is produced at the lower end of the rope. The wavelength ofthe pulse when it reaches the top of the rope is λ2. The ratio λ2/λ1 is-am1+m2 m2b m2m1c m1+m2 m1d m1m2
